So I decided to do a little test yesterday and send a BTC transaction and a BCH transaction at the same time.
Just to make it interesting and give BCH an unfair advantage I decided to set the BTC fee at half the reccomended amount, at around 500 sat/byte. The estimated time for confirmation was 25 BLOCKS or more than 14 hours.
Guess how long the low-fee BTC transaction took???
Well I guess you are just lucky, I have no idea how this described above situation could've happen, because I've recently paid a transaction fee, which was a little bit less, than recommended (as I recall, recommended was about 10$ and I paid about 7$) and it is still pending! It is the 5th day now. It was then, when I realized how useful ethereum can be, because ETH transaction took me really less than 10 minutes and was very cheap.
